    • Techniques or processes for producing assemblies using adhesives and substrate material, such as glass. In one embodiment, the assemblies may be for portable electronic devices. For example, a cover glass of a portable electronic device may have a first layer of a self-leveling adhesive, which may be adhesively coupled with the cover glass. A second layer of a second adhesive, which may be different than the self-leveling adhesive of the first layer, may be adhesively coupled with the first layer. An optical component may be adhesively coupled with the second layer, so as to secure the optical component. The first layer may be cured prior to securing the optical component, so that the optical component may be substantially isolated from stress effects of adhesive cure shrinkage of the first layer. Flexure, warpage or optical distortion of the optical component due to adhesive cure shrinkage may be substantially avoided.
    • 使用粘合剂和基底材料(例如玻璃)生产组件的技术或工艺。 在一个实施例中,组件可以用于便携式电子设备。 例如,便携式电子设备的玻璃罩可以具有自流平粘合剂的第一层,其可以与盖玻璃粘合地联接。 可以与第一层的自流平粘合剂不同的第二粘合剂层可以与第一层粘合地结合。 光学部件可以与第二层粘合地耦合,以便固定光学部件。 在固定光学部件之前,第一层可以被固化,使得光学部件可以基本上与第一层的粘合剂固化收缩的应力作用隔离。 基本上可以避免由于粘合剂固化收缩导致的光学部件的挠曲,翘曲或光学变形。
